SCHOTT CERAN® quality testing

Our standards are measures in millimeters and microns.

SCHOTT CERAN®: with high quality to global success.
For us at SCHOTT, the big picture isn’t the only thing that’s important, but also minor details. We rely on state-of-the-art manufacturing techniques and the highest possible standards for quality to produce our cooktop panels. Raw glass manufacturing alone is meticulously monitored at more than 5,000 measurement points. You can therefore be sure that no cooktop panel ever leaves our plants without being inspected by highly sensitive laser technology and the glance of our highly qualified personnel that has proven itself millions of times.

Only a truly perfect cooktop panel ever receives our seal of quality, the SCHOTT CERAN® logo, at the end of an equally painstaking and environmentally-friendly production process.

  1. A special mixture of raw ingredients is melted into molten glass at a temperature of 1600 °C (2912° F).
  2. 
The raw glass in liquid form is rolled into the desired thickness.
  3. The glass is gradually cooled down from a temperature of 900 °C (1652° F) to 100 °C (212 ° F) while the residual tension is released. 

  4. Now the glass can be cut and subjected to one final quality inspection. 

  5. Glass manufacturing is finished. The glass is now ready for processing.

  1. The glass surface is cut.
  2. 
Next, it is ground and the holes are drilled. 

  3. The cooktop panels are printed to suit the individual needs of the appliance manufacturer.  

  4. A glass-ceramic is produced during the ceramization process.
  5. The glass-ceramic cooktop panel is shipped to the appliance maker after the final inspection so that they can install our cooktop panel in their product. This is how it gets delivered to your home.
